[BH] Some rooms don't have outline/don't allow room type assignment

I have similar a similar issue. Multiple times, the room the stairs lead up to has ended up not having/losing the ability to be assigned a room type (residential/public/employees). 

I managed to restore it previously, but gave up when expanding the house one tile in width. It was somehow fine without the railing along the top of the stairs, but when closing the railing (in the position indicated by the wall tool in the second picture) it would turn into an ordinary room without any coloured outline. I tried to do it in a variation of ways to see if anything worked, but the same thing would always happen - whenever that one tile long piece of fence was placed, there'd be that thunk with dust coming out from around the room, as if completing it, though the outer walls remained untouched. 

Edit: restarting the game fixed it for me:

So I made a new lot with downstairs as my buissnes and upstairs as my residential. For some reason 2 rooms don't have an option to be assigned. 

they are big rooms (the residential is basicly one big room and the downstairs too) is there a way for me to still have this lot work cause im really proud of my work. 

im playing on pc if thats important

I am creating a residential home business and there is a bug where I have set a room to being a "public" space, but once I put a frieze on top of the room and change floors the option to set the type of space is no longer available and the room is no longer highlighted as a public space with a unit outline.

I've also been having this problem. Restarting has solved it every time so far.

I have the same problem. Have a little video of it.

Edit: I put the railings in and the room was not assigned anymore. Then i saved and restarted. And the room was assigned with the railings in place. 

Hey Everyone, 

Has anyone come across a glitch when trying to run a small business on their lot the tab where you determine which rooms are for employees, family and customers is glitched. No drop down menu to be able to choose.

Just finished making a lot and I'm trying to assign small businesses to each room but I can't get the window drop down to appear.

I'll click the room but there is no outline appearing. And I continue to get the kiosk not accessible pop up. 

I play on Xbox S

Im trying to build a residential small business lot and just got the hang of zoning the units, but when i added an exterior trim to the building, suddenly the room inside lost its unit outline and its unit type couldnt be changed. removing the trim fixed it, but id like to have the trim on the outside and still be able to zone that unit correctly.
